Add SDK features to all Ralph loop recipes

- Add WorkingDirectory/working_directory to pin sessions to project root
- Add OnPermissionRequest/on_permission_request for unattended operation
- Add tool execution event logging for visibility
- Add See Also cross-links to error-handling and persisting-sessions
- Add best practices for WorkingDirectory and permission auto-approval
- Consistent across all 4 languages (Node.js, Python, .NET, Go)

 6. **The plan is disposable**: If the agent goes off track, delete `IMPLEMENTATION_PLAN.md` and re-plan
 7. **Keep `AGENTS.md` brief**: It's loaded every iteration — operational info only, no progress notes
 8. **Use a sandbox**: The agent runs autonomously with full tool access — isolate it
+9. **Set `WorkingDirectory`**: Pin the session to your project root so tool operations resolve paths correctly
+10. **Auto-approve permissions**: Use `OnPermissionRequest` to allow tool calls without interrupting the loop
